You should specify the level of res based on the effect of the res on the end-use of the product. J-STD-001 defines cleanliness requirements for ALL flux types, including water soluble and no-clean that you mention. 1 There is no equivalency betwee

Asoe, The systems you are describing are Resistivity of Solvent Extract (ROSE) Testers. These systems are available using one of two technologies, Static or Dynamic. Both systems use a calibrated test solution comprised of IPA and DI water. The t

Hi Davef, if by using Omegameter 600 SMD I am reading 1,56 microgram NaCL/sqcm, what is the real value I am measuring? considering the 14 sensitivity ?

Dave, Ionic contamination testers are considered to be a valuable tool to determine the cleanliness of both bare boards and post solder boards. There are some instances when SIR testing is more suitable for determining cleanliness than ionic contamin

If No-Clean flux does not need to be cleaned, then why do I get readings of up to 27(ug NaCl/sq in) on boards that are not washed, up to 23.4(ug NaCl/sq in) on boards washed with DI water only and from 1.2 to 10.1(ug NaCl/sq in) on boards washed with

Yes, the OmegaMeter and IonoGraph are test equipment to measure ionic contamination. Either of those units should enable you to sort your inventory boards. for more info about this equipment, go to: www.cooksonee.com/products/scs/CoatingSystems/Ionic

Both are equally efficient process control tools. Neither is particularly effective in testing ionic contamination. The best way to sell your customer on allowing you to do this is to show them that you understand the WHOLE process and are able
